Price Comparison

The BenQ TH575i 1080p Home Projector is priced at £479.00, while the Smart Projector Mini Portable Projector is significantly more affordable at £189.99. This price difference of £289.01 may be a deciding factor for budget-conscious consumers. The BenQ model positions itself as a premium offering with enhanced features, justifying its higher cost, whereas the Smart Projector aims to deliver a solid performance at a fraction of the price, appealing to those seeking a value option.

Image Quality

When it comes to image quality, the BenQ TH575i boasts a brightness of 3,800 lumens, ensuring clear visuals even in lit environments. This high brightness allows it to project a vibrant 120-inch image, making it ideal for home cinema experiences. On the other hand, the Smart Projector Mini Portable Projector offers native 1080p resolution with 4K decoding capabilities. While it excels in portability, projecting a 100-inch image from only 8.6 feet, it may not match the brightness of the BenQ model in well-lit settings.

Portability

Portability is a standout feature of the Smart Projector Mini Portable Projector, which is designed to be compact and lightweight, weighing just 860 grams. This makes it easy to carry in a backpack for outdoor movie nights or travel. In contrast, the BenQ TH575i is a more traditional home projector, lacking such portability. Its installation may require a designated space, making it less convenient for users who desire flexibility in their viewing locations.

Setup and Installation

The BenQ TH575i offers flexible setup options with its 1.1x optical zoom and Auto Vertical Keystone correction, allowing for easy placement and a perfectly squared image without complicated installation. This feature is particularly beneficial for users who may not be tech-savvy. Conversely, the Smart Projector Mini Portable Projector features a 330° rotatable stand and a short throw ratio, which simplifies setup for various projection angles. However, it relies more on manual adjustments compared to the automatic features of the BenQ.

Streaming Capabilities

In terms of streaming capabilities, the BenQ TH575i includes a licensed Google TV dongle, providing seamless access to popular platforms like Netflix, YouTube, and Disney+. This integrated solution enhances the user experience by eliminating the need for additional devices. Meanwhile, the Smart Projector Mini Portable Projector also supports streaming through 1,000+ apps, including major services like Netflix and Prime Video, but it doesn't come with a dedicated dongle, potentially complicating setup for some users.

Gaming Performance

For gamers, the BenQ TH575i's ultra-smooth 16.7ms low input lag is a significant advantage, ensuring responsive gameplay without annoying delays. This feature makes it an excellent choice for those who enjoy fast-paced gaming. The Smart Projector Mini Portable Projector, while capable of delivering 1080p visuals, does not specify its input lag, which may raise concerns among serious gamers about its performance in high-stakes scenarios.

Versatility

The BenQ TH575i features four different viewing modes—Cinema, Sports, Game, and 3D—tailoring the experience to various entertainment needs. This versatility is a strong selling point for users who appreciate customisation in their viewing experience. Meanwhile, the Smart Projector Mini Portable Projector offers AI-driven auto focus and 6D keystone correction for a more user-friendly operation. While both projectors offer unique advantages, the BenQ's variety of modes may appeal more to dedicated home cinema enthusiasts.

Which should you buy?

Choosing between the BenQ TH575i 1080p Home Projector and the Smart Projector Mini Portable Projector ultimately depends on your specific needs and budget. If you're looking for a high-performance home cinema projector with robust features and superior brightness, the BenQ TH575i is the clear choice at £479.00. However, if you prioritise portability, affordability, and basic streaming capabilities, the Smart Projector Mini Portable Projector at £189.99 offers excellent value. Consider your primary use case to make the best choice for your home entertainment setup.
